You can only apply load combinations to gravity combinations, as lateral and seismic combinations do not consider pattern loading. For detailed information on how to apply pattern loading to load combinations, see the following instructions.

1. On the Load tab, click Combination.

   The Loading dialog opens on the Combinations page. On this page, you can see all currently existing load combinations.

2. On the left side pane of the Loading dialog box, select the name of the load combination.
3. In Parameters, ensure that the Pattern option is selected.
4. Click OK.
   Note: If you wish, you can use pattern loading for every gravity combination in your model. However, doing so may create many additional combinations.
